What is an Impulse Sealer?

An impulse sealer heat-seals objects by sending high current on impulse to a heater ribbon, equipped on the surface of the heat-sealing blade, to generate heat that enables thermal-sealing through thermal conductivity. The section to be sealed is placed between the heat-sealing blades, pressed and thermal-fused when current and heat are delivered on impulse through the heater ribbon. After the current stops the seal remains under pressure to cool and to give it a clean finish.

What’s So Good About An Impulse Sealer?

Impulse seal is ready to use:

This is no warm-up period after turning it on.

Impulse seal is economical:

Electricity for the heater is only used during the sealing process.

Impulse seal poses little risk of burn injury:

No component is always hot.

Impulse seal creates a seal with a clean slate:

Cooling and fusion takes place under pressure.

Constant heat sealer requires waiting time for the hot bar to heat up. This also means additional power is wasted.

Constant heat sealer must maintain the sealing bar hot at all times. Power is constantly drained as long as the switch is on.

Constant heat sealer maintains the sealing area hot at all times, exposing the user to a higher risk of accidentally touching the hot bar.

Constant heat sealer merely provides heat, leaving cooling and fusing process to take place while the package material is shrinking. This results in a rather uneven finish.

A Variety of Sealers

Our machines seal the openings and loose ends of plastic packaging materials (such as bags). In addition to impulse sealers, sealers include the constant heat sealer, the ultrasonic sealer and the high-frequency sealer.
